Primeiro, remova as configurações feitas por você.

sudo rm /etc/modprobe.d/rtl8723be.conf

Se você não tiver esse arquivo, nada está errado.

Em seguida, instale um bom driver

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

Reinicie e aproveite

Se você ainda tiver problemas (sinal baixo), talvez seja necessário adicionar uma opção:

echo "options rtl8723be ant_sel=2"  | sudo tee /etc/modprobe.d/rtl8723be.conf  

ou

echo "options rtl8723be ant_sel=1"  | sudo tee /etc/modprobe.d/rtl8723be.conf
